bio
endocytosis/exocytosis
what 3 things do eukaryotic and prokaryotic have in common?
plasma membrane, ribosomes, and cytoplasm
3 types of plastids
chloroplast
chromoplast
leucoplast
Hypotonic solution
low solute concentration
(high water concentration)
swells and burst
Hypertonic solution
has high solute concentration
(low water concentration)
wrinkles
what can't cross the membrane?
large or charged molecules, need protein channel.
what can cross the membrane?
gases, hydrophobic, small, and uncharged molecules.
cytoplasm
jelly like substance, helps with movement inside cell and gives cell its shape.
cytoskeleton
supporting network of long protein fibers that form a framework for a cell. movement of organelles inside the cell
Rough ER
isotonic
same water concentration, cell stays the same
plasma membrane
lipid layer (phospholipid) around the cell that decides what comes in/out of cell.
concentration
amount of solute within a solute
concentration gradient
difference in concentration of molecules in 2 areas
transport proteins
protein that helps transport substances from outside to inside, inside to outside
Vesicles
organelle used for transport of resouces
Vacuoles
Animal cell- used for storage of resources
Plant cell- central vacuole stores water in center
smooth ER
Makes lipids, helps with detoxification, no ribosomes
sodium potassium pump
active transport in our bodies, helps rid our cells of sodium
Peroxisomes
organelle in charge of the breakdown of fatty acids/hydrogen
centrioles
long fibers (microtubes) in charge of cell divison
lysosomes
organelle responsible for hydrolysis reactions
breaks down/cleans up debris
Hydrogen peroxide
byproduct of many metabolic reactions in cell
mitochondria
powerhouse of cell, cellular respiration/cellular energy
cell wall
rough rigid outer wall made of cellulose
provides support/structure to plant cell
